1）Be型（即系动词原型be+表语+其他）。
如：Be quiet,please.
否定句Don't + be+表语+其他。
如：Don't be angry.
2）Do型（即系动词原形+宾语+其他）。如：
Open you books,please.
否定句Don't +实义动词原形+宾语+其他。
如：Don't eat in the classroom.
3）Let型（即Let+宾语+动词原形+其他）如：
Let me help you.
Let's=Let us go at six o'clock.
否定句一般在宾语后加not.如：
Let' not watch TV.
4）No+V-ing型（此种形式通常用于公共场合的提示语中，意为“禁止做某事”）如：
No smoking! 严禁吸烟！
No talking! 不许交谈！
No passing! 禁止通行！

5. We can eat in the cafeteria. We can't eat in the classroom. （用but 将两句话连接起来）
参：
一，单选
1. 答案为B.此句为B型祈使句，因为late为形容词。其否定形式为“Don't be+形容词”.
2. 此句为L型祈使句，以动词原形Let开头，意思是“让我们唱歌吧”,故答案为B.
3. 答案为A.因为此句没有宾语，arrive 不用带介词，而reach为及物动词，应带宾语。故不选C.
4. 句子意思为“我听，但我什么也没听见”,前面的空表动作，应用listen,后面的空表结果“听见”,应用hear,故答案为A.
5. 答案为D.此题是介词短语作定语修饰girl,表示“穿红连衣裙的女孩”.
6. 答案为C.第一空作否定回答用no,而第二空eraser前无冠词，故不能用not,应用no.
7. D 8. C 9. C 10. A 11. B
12. C 13. B 14. C 15. D 16. B
二、完型填空
1.否定句：We can't wear hats in school.
疑问句：Can you wear hats in school?
肯定句：Yes, we can. 否定句：No, we can't.
因为can为情态动词，故变否定句直接在can后加not,变一般疑问句直接将can提到主语之前。
2. no后接动名词形式，故答案为taking.
3. can speak. can的同义词为be able to.
4.We can't wear hats in school.
5.We can eat in the cafeteria, but we can't eat in the classroom.
